10 Claims.

The present invention relates to toilet seats and more particularly toauxiliary toilet seats adapted for use by small childrfln.

An object of the invention is to provide a childs toilet seat whichadapted for attachment to an adult toilet seat, and which is compactlyfcldable to a position adjacent to the 1111-. derside of the covermember, so as to permit nor.- mal use of the adult toilet seat.

Another object is to provide a child's toilet seat which can be mountedin a simple manner and which is capable of easy folding and um folding.

A further object is to perfect details of construction generally.

The invention further consists in the several features hereinafterdescribed and claimed.

In the drawings, designates a conventional .closet bowl on which ismounted a conventional hinged toilet seat, the latter comprising a seatmember 21 and a cover member 22 provided at their rear portions withhinge members 23 which are pivotally connected by pintles 24 to upstandins bracket bolts 25 rigidly secured to the bowl. The seat member 2i,which is designed for adult use, consists of the usua1 rim with arounded upper surface, and is here shown to be of the closedfront type,although an open-front seat member of conventional type may be usedinstead.

In accordance with the invention, an auxiliary or child's toilet seat,designated generally by the number 26, is associated with the adult seatand includes a dished seat member 21 of generally oval shape whichdetachably nests into the adult seat member 2|, the auxiliary seatmember having a concave bottom surface 28 to fit the rounded surface ofthe adult seat member. A back rest or plate 29 is connected by a springhinge 30 to the rear end of the auxiliary seat member 21, the hingehaving a coiled torsion spring 3!, Figs. 2 and '6, tending to move theauxiliary seat memher and back rest angularly apart. The marginalportions 32 of the back rest are offset rearwardly. A pair of sideplates 33 are co nected by hinges 34 to the opposite side portions ofthe auxiliary seat member 21, and are swingable upwardly to parallelvertical positions, as seen in Figs. 1, 2, 4, and 5. The side plates areshaped to fold inwardly about parallel hinge axes to a nested positionwithin the dished auxiliary seat member, as indicated in Figs. 6 and '7,and in this position the hinged back rest is foldable over the sideplates and nests into the folded side plates. The auxiliary seat member,back rest and side plates are preferably formed wholly or mainly f ahardened plastic material such as Bakelite. The

back rest and side plates are connected by fiat brace bars 35 each ofwhich at one end is hinged at 36 to a bracket or car 31 swiveled at 38to t it?v marginal portion of the back; rest, and which at the other endis hinged at 3,9 to a bracket or ear 40 swiveled at M to the upper edgeportion of the associated side plate. In the folded posi-. tion of theparts the flat brace bars 35 are interposed between the side plates andthe back r s as se is Fi the ide plates havin marginal notches 42 attheir dished edges and recesses 43 at their upper edges to accommodatethe brace bars. The side plates, when in their upstanding position, havetheir front portions connected by a metal cross strap comprisingcomplementary flat bars 44 and 45 each of which is hinged at 46 at itsouter end to a bracket or ear 4'! swiveled at 48 on the outer side ofthe associated side. plate, there being a recess 49 in the side plate toaccommodate the ear. The cross bar 44 has spaced end knuckles 50carrying a cross pin 5i detachably engageable by a, terminal hook 52 onthe bar 45, and the two cross bars are held down in aligned position bycoiled torsion springs 53 on the respective hinges of the bars. In. thefolded condition of the auxiliary seat the swiveled cross bars extend inrabbets 54 formed along the outer sides of the side plates and are heldtherein by the torsion springs 53.

In some instances, the auxiliary seat member 21 is provided at its upperfront portion with a deflector plate 55 which is hinged at 56 at itsrear edge and is frictionally retained in position, the deflector platebeing bent to conform to the contour of'the seat member.

The back rest 23 is connected by a link 51 with a mounting plate 58which is adapted to be secured to the underside of the cover member 22of the adult seat, the link having a hinge connection 59 with the backrest and a hinge connection 63 with the mounting plate, the axes of thehinge connections being parallel with the axis of the hinge pintles 24.The hinge connection Bil is provided with one or more torsion springs 6|tending to urge the back rest away from the mounting plate. In theunfolded position of the auxiliary seat, seen in Fig. 1, the back rest29 is approximately parallel to the cover member 22. The mounting plate58 has a rim or bead 82 adapted to conceal the edge portions of theauxiliary seat when the latter is folded, the rim or bead beingpreferably formed mainly of a hardened plastic material. If desired, themounting plate may be attached to the cover member by screws, not shown,slots 63 being provided in the plate for this purpose. The mountingplate is here shown to be adjustably secured to the cover member bypairs of hook members 64 engaging opposite side edges of the covermember. Each hook member bears on the mounting plate and is guided by astud 65 which is secured to the plate and extends in a slot 66 in thehook member. A pair of levers 61 are pivotally secured at 68 to eachside of the mounting plate and bear on the respective hook members, thehook members and levers having cooperating roughened clamping surfaces69 and 10. The pair of levers are confined by a cover plate H which issecured to the mounting plate 53 and is disposed in a recessed part ofthe rim 62. Each cover plate has detents 12 to engage recessed parts ofthe levers when the latter are in their closed position. The cover platealso has a notch 72' at its inner edge to facilitate outwarddisplacement of the levers. If desired, the rim may be provided withinset rubber bumpers 13.

The front end of the rim or bead 32 carries retaining means, Figs. 9 and12, to hold the folded auxiliary seat within the rim. The retainingmeans is here shown to include a suitably guided forwardly projectingpush slide 14 which is urged outwardly by an arched leaf spring 15. Apair of fingers it are pivoted at H in the rim and have inwardlyprojecting end portions 18 to engage the front edges of the auxiliaryseat member 21.

to the mounting plate 58 to engage the rear por-' tion of the foldedauxiliary seat member, the back rest 29 being suitably apertured to passthis finger.

To install the auxiliary toilet seat 26 on the adult toilet seat, theformer is folded flat and rested on the adult seat member 2! to nesttherein, the levers 61 being swung outwardly. The cover member 22 isthen lowered onto the mountingplate 58, and the hook members 64 are thenpushed inwardly against the edges of the cover member. The lockinglevers 6'! are then pushed inwardly to their locked inner positions,causing the hook members to grip the opposite side edges of the covermember. The assembly is then ready for use. When it is desired totransfer the auxiliary seat to another toilet seat, the auxiliary seatcan be readily detached by swinging out the locking levers 31. Theauxiliary seat can be installed without the use of tools and withoutmarring theadult seat.

When the conventional toilet seat is to be used by an adult, theauxiliary seat is folded and latched on the mounting plate, as seen inFigs. 3, 6, and 7, whereupon the auxiliary seat will swing as a unitwith the cover member 22. When the auxiliary seat is to be used, it isunlatched from the mounting plate preferably while the cover member isin its horizontal position, shown in Fig. 7, whereupon the cover memberis raised to the approximately vertical position shown in Figs. 1 and 2,causing the auxiliary seat to unfold. In this operation, the springhinges 33 and 60 tend to open the linkage and keep the auxiliary seatmember 2! nested in the main seat member 2|. After the child is seatedon the seat member 27!, the cross straps 44 and 45 are swung inwardlyfrom the side plates 33 and are joined by the hook connection 5|, 52,thus preventing the child from falling. The auxiliary seat member 21 ishere shown to have a closed front, but insome cases this seat member mayhave an open front.
